Revelation 21:12-13

Also she had a great and high wall with twelve gates, and twelve angels at the gates, and names written on them, which are the names of the twelve tribes of the children of Israel:  three gates on the east, three gates on the north, three gates on the south, and three gates on the west.

• ·        The wall for security.  Heaven is a safe state.  (MH)

• ·        The height of it is sufficient both for ornament and security (MH)

• ·        Twelve gates – answering to the twelve tribes of Israel (MH)

Psalm 69:28  Let them be blotted out of the book of the living, and not be written with the righteous.
